On the final Billboard Pop Shop Podcast of 2020, hosts Katie and Keith team up with Ask Billboard columnist Gary Trust to answer questions from chart fans. Which woman has the most No. 1 albums on the Billboard 200 chart? What about the all-female group with the most chart-toppers? And where does Taylor Swift, now that she has an eighth No. 1 with "Evermore," fit into the list? Those questions, and more, are answered on the latest Pop Shop Podcast.
